Green tea leaf

Green tea leaf comes from the Camellia sinensis plant, native to East Asia. The leaves are processed through steaming or pan-firing to prevent oxidation, preserving their green colour and characteristic flavour. It is the basis for many types of tea, including sencha, matcha, and gunpowder.

Green tea leaf is primarily used for its distinct flavour and aroma in beverages like kombucha, ready-to-drink teas, and flavoured waters. It is also included in some food supplements for its perceived health benefits, often in powdered or extract form.

Green tea leaf is not typically considered a food additive in the UK. It is a natural foodstuff. Research into the health effects of green tea consumption, particularly its antioxidant compounds like catechins, is ongoing. Some studies suggest potential benefits, while others show mixed results. Regulatory bodies like EFSA have evaluated green tea extracts in different contexts, but green tea leaf itself is not subject to the same additive regulations.
